Blower inducer works, switches work. 115 volts goes to controller board. When I measure igniter feed lines they show 3 volts and once blower stars it max up at 6 volts. Is this a board problem? Do I need to read 24v or 115v? My igniter is 41-404. If I buy it can I just transfer the wires from old to new? Not electrical engineer. Thank you

You should be getting 115v at the igniter when it is energized. This will be AC, not DC, so that might explain your low readings.

The new igniter will have its own wires, so it is a simple thing to replace. Just be careful, the black part is quite fragile.

Good luck,
